In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of installation method of large-scale impingement type hydraulic generator group casing, it comprises the following steps：
(1) casing and steady boom girder are assembled, and the both ends of steady boom girder are poured in base concrete,
After casing and the assembling in place of steady boom girder, precision adjustment is carried out to the center of casing flange face, elevation, horizontal level, so
Positioning is supported casing using section steel manufacture well type stent afterwards, the lower end of stent be supported on steady boom girder and with steady water
Grid girder is fixedly connected, and upper end is contacted with the flange face of casing；And strut is set to reinforce casing in well type frame upper
Support, well type stent and the contact position of strut and casing are welded；
(2) after the completion for the treatment of cabinet supports positioning, carry out concreting, in casting process, concrete need uniformly, it is symmetrical under
Material, is aided with the flange face deflection on dial gauge monitoring casing top, adjusts concrete discharging orientation and speed in time；
(3) after the completion of concreting, well type stent and its strut on steady boom girder are removed, with the water with micrometer head
The levelness in quasi- instrument measurement casing upper flange face, micro grinding process is carried out to the flange face for being unsatisfactory for requiring.
Preferably, the perpendicular support that the strut includes support machine casing top bevel and lower end is overlapped with cabinet sides, with
And the horizontal support of support machine casing top adjacent bevel surfaces；The horizontal support two is one group, is connected by connecting rod with well type stent,
The perpendicular supporting welding is in horizontal support.
Preferably, the well type stent is made of the welding of 200 ㎜ I-steel.
Preferably, the steady boom girder is made of the welding of 280 ㎜ I-steel.
Preferably, the strut uses 160 ㎜ I-steel.
Compared with prior art, the invention has the advantages that：
1st, the present invention can effectively increase construction efficiency, accelerate construction progress, and shorten the duration of construction.
2nd, the present invention substantially reduces deformation of sedimentation of the casing in concreting process, effectively reduces installation wind
Danger.On the other hand, deflection diminish without using lathe reprocess, reduce Work tool input cost, effectively increase through
Ji benefit, has especially saved purchase, the cost of transportation of the Work tool of overseas project.
3rd, installation method of the invention has low cost, speed of application is fast, cost savings are notable, is impact type machine at home and abroad
Group installation provides the characteristics of convenient.
